Genotype and Phenotype Characteristics of Chinese Pediatric Patients with Primary Hyperoxaluria.

ABSTRACT: Primary hyperoxaluria (PH) is a rare monogenic disorder characterized by recurrent kidney stones, nephrocalcinosis, and renal impairment. To study the genotype and phenotype characteristics, we evaluated the clinical data of 42 Chinese pediatric PH patients who were diagnosed from May 2016 to April 2022. We found that patients with the PH3 type showed an earlier age of onset than those with the PH1 and PH2 types (1 versus 5 and 8 years, respectively, P < 0.001). Urine citrate was significantly lower in PH1 and PH2 patients than that in PH3 patients (91.81 and 85.56 versus 163.9 μg/mg, respectively, P = 0.044). Spot urine oxalate levels were slightly higher in PH1 than that in PH2 and PH3 patients (457.9 versus 182.38 and 309.14 μg/mg, respectively, P = 0.
